What is an Electric Driveline Retarder do?

It's an electromagnet that can in front of the transmission

2 / 30

Wing mounted directly to the relay of the axle group

On the wheel itself

3 / 30

What do ABS brakes do?

Allows for shorter stopping distances

None of the above

Prevents wheel lock-up and skids

Allows for a by-pass of the air brake system

4 / 30

What is Automatic Traction Control (ATC)?

None of the above

It allows the tires to grip the road better

It uses ABS sensors to monitor drive-wheel spin on slippery roads

It slows down the vehicle to a crawl

5 / 30

What does a steady ABS dash light indicate?

The vehicle has just been started

A self-test is being performed

It's supposed to stay lit

A problem with the ABS system

6 / 30

At what point do air brakes generate the most ongoing heat?

Braking from a high rate of speed

Travelling on downgrades

None of the above

Braking in rainy conditions

7 / 30

Brake management systems are effective, when should drivers rely on them?

At higher speeds

Never

With heavy trailer loads

Only in poor weather

8 / 30

When were ABS brake mandatory on all air brake trucks, buses and trailers?

Since 1992

Since 2000

Since 2010

They're not mandatory

9 / 30

If speed increases on a downgrade, what should you not do?

Repeat this process as necessary until the retarder can maintain the speed without service brakes

Use a splitter valve

Continue down the hill using the auxiliary retarder to control the speed

10 / 30

To descend safely in rural areas, which statement is false?

Follow the actions of all the other drivers

Use 4-way flashers and stay in the right lane when possible

Follow advisory speed limits

Use the vehicle's auxiliary retarder

11 / 30

What is the biggest challenge for combination units causing the loss of brake balance?

An uneven load distribution

Low tire pressure

Loss of air pressure

Windy conditions

12 / 30

With regard to ABS, which statement is false?

If the tractor or trailer do not have ABS, use a light, steady braking technique

ABS brakes work with air brakes and hydraulic brakes

ABS brakes are different with hydraulic brakes compared to air brakes

Make sure you know which units in a combination have ABS

13 / 30

When using tire chains, what is not recommended?

Maintain normal speeds

In extreme conditions, it may be safer to park

Ensure they are correctly sized and tightly installed

Stop and check tightness after moving one vehicle length

14 / 30

What are Hydraulic Driveline Retarders similar to?

Torque converters

Transmissions

Clutch plate

Nothing

15 / 30

What potential problem can happen while applying brakes on combination vehicles?

Skids or jackknifes

Wider turns

Nothing in particular

Longer stopping distances

16 / 30

What is the cause of almost all of the brake failures and runaway crashes?

No pre-trip inspections

Malfunction of a primary air cylinder

Poor maintenance

The brake system's inability to handle excessive heat

17 / 30

What's another work for jackknife?

Pull

Yaw

Yank

Push

18 / 30

To brake safely with ABS, what should you not do?

Be cautious when steering around objects

Pump the brakes

Apply firm, steady pressure to the brake pedal

Read the manufacturer's operational manual for instructions

19 / 30

The brakes under the empty rear of the trailer receiving the same amount of application air pressure as the drive axles, without the load to hold them down onto the ground, what can happen?

None of the above

Longer braking distances

May cause the rear of the trailer to slide and swing

Wheel lock-up

20 / 30

When descending on unfamiliar grades, which statement is false?

On extreme grades, change gears often

Select a low gear and turn on the retarder before the hill is crested

Stay in a low gear until the steepest part of the descent

There is a balance between the retarder, speed, load and grade is reached

21 / 30

What does a flashing ABS dash light indicate?

None of the above

Controlling the service brakes

The vehicle has just been started

A problem with the ABS system

22 / 30

What do exhaust retarders essentially do?

To help block the flow of exhaust

To help the back pressure stays within the engine's back pressure capacity

To help dissipate the exhaust

To help the back pressure move

23 / 30

What does water in the brake drums cause?

Acts as a lubricant

Nothing

It cools down the rotors

Reduction in braking ability

24 / 30

When do auxiliary retarders work best?

At lower vehicle speeds, and with the engine just under the rated rpm

At normal speeds

At higher speeds

Whenever you want them to work

25 / 30

If approaching a large amount of water on the road, what should you not do?

Test the brakes after exiting the water to help to dry them out

Apply slight constant pressure to reduce the amount of water entering between the brake drums and shoes

Reduce speed and cover the brake pedal when approaching

Maintain speed to keep momentum

26 / 30

What will a heavy load at the front of a trailer will cause the drive axles to have?

No difference compared to weight at the back of a trailer

Better steering ability

Good traction for pulling and braking

More momentum to get up to speed

27 / 30

When using runaway lanes, which does not apply?

A narrow steep runaway lane will be very difficult to use if the vehicle is out of control

You may use these lanes for other purposes

Use the lane before the vehicle is out of control

Use the lane when the brakes no longer control the descent

28 / 30

While braking on icy roads, what is not recommended?

Icing chains to create better traction

Using snow tires to create better traction

Locking the wheels slightly to create friction and better traction

Light braking to allow for a slow control stop

29 / 30

When should the driver check the ABS light on the trailer?

Never

After hearing the ABS activate

While parked

After start-up and occasionally when braking

30 / 30

Trailers equipped with ABS brakes will have an ABS warning light. Where is this light located?

At the rear of the left side
